Add a workaround for a bug when setting the Raspberry GIO config and state

The Raspberry Pi GPIO config and state messages incorrectly return with
the tag length set to 0. We then check this value to have the response
flag set. Work around this by setting the response flag when setting the
GPIO config or state and this value is zero.
